智能变电站过程层电力专用交换机应用分析
|
摘要
随着智能变电站通信网络的业务剧增,过程层网络因其薄弱的故障定位能力,一定程度上增加了工程部署和电网运维的工作难度。文章结合智能变电站过程层通信的需求和特点,介绍了一种基于SCD文件实现自动配置、即插即用、二次回路安全隔离和全路径监视的电力专用交换机,并通过应用实例验证了其有效性和可行性;这使得交换机不再游离于监控系统之外,无缝嵌入到智能变电站控制系统,进一步提高了智能变电站的监控和运维水平。
With the business of intelligent substation communication network increasing rapidly, the process layer network increases the difficulty of project deployment and power grid operation and maintenance to a certain extent due to its weak fault location ability. Combined with the requirements and characteristics of process layer communication of intelligent substation, this paper introduces a kind of power private switch based on SCD file to realize automatic configuration, plug and play, secondary circuit security isolation and full path monitoring, and verifies its effectiveness and feasibility through application examples. This makes the switch no longer free from the monitoring system, seamlessly embedded into the intelligent substation control system, further improving the monitoring and operation level of the intelligent substation.
